Appearances and Meetings

Below are the user groups, conferences and any other public events that I will be at and whether I am presenting or not. If you see me, come over and say “hi”, it’s always nice to chat face to face. I hardly ever bite…
I don’t include London Oracle Beers as that just resulted in way too many entries!

Future Events

Past Events

12th June 2018
A trip to the Romanian Oracle User Group where I presented on Instrumentation and why it is so vital.

29th-31st May
Riga Dev Days
I was delighted to have been accepted to speak at the Riga Dev Days, which has become a very popular event. I’ve never been to Lativa before so this was an especially interesting event for me
Wednesday 30th 18:00 How to Improve Your Code, Your Database, Your Life on instrumenting your code, your application, and making the future of the system much, much better.

22-23rd March
OUG Ireland conference
I did two talks and a panel session:
Thursday 22nd 12:10 How to do Performance Tuning which is more about the philosophy of performance tuning than actual individual skills. Many people know some of the skills, but the process of performance tuning is a much rare skill.
Friday 23rd How to Improve Your Code, Your Database, Your Life which is about one of my favourite annoyances – that people so often do not instrument their code or applications, and rarely in a systematic manner.
Friday 16:25 Panel Session on 18C and everything else. The Irish conference traditionally ends with an open panel session, which before now has run on for almost 2 hours until the last people escape home or go to the pub.

22 February 2018
I am deputy chair of this SIG and I was also presenting on Physically Clustering Data for Phenomenal OLTP Performance

22-23 Jan 2018
ilOUG – Israel Oracle Uer Group.
I presented on:
The Heart of Oracle – How Does the Core RDBMS Work

The UKOUG Tech17 Conference.
This is my “home” conference. For the first time in many years I had not been involved in the organisation of the event and I did not even giving a normal presentation. However, I did some chairing.
Tuesday 5th: I’ll be one of the Question Masters for Jonathan Lewis’s CBO panel session. It’s becoming a tradition!
Tuesday 5th: Dev Vs. DBA Vs. DevOps roundtable. We will discuss the traditional divide between Development & DBA and how it can be better handled.
Update: Tuesday 5th, 10am. I went to a roundtable “argument” by Bryn Llewellyn & Kamil Stawiarski – and got pulled up to be a third party.

21-24th November
DOAG 2017 Conference
This was my second trip to what is now the largest Oracle Tech conference in Europe. I did two presentations (it was supposed to be three but I had to cancel one as illness prevented me preparing it):
Tuesday 21st – The Heart of Oracle – How Does the Core RDBMS Work

The session “Heart of Oracle” was totally full and I was asked to repeat it later in the day.

The Heart of Oracle – How Does the Core RDBMS Work

I did the one talk, “Martin Widlake Goes Wild: TOP 10 Ways of Drinking Beer, Combined with Top 10 Ways of Bad Programming Habits. Because You Can’t Talk About It Being Sober”.

Little POUG – Myself and Neil Chandler flew over to Poland to do an evening user group. Ami Aharonovich complete the agenda. I presented “When Things Go Wrong – My Career So Far”, which is a variation on my Disasters talk and how you can help avoid them. (The disasters, not my talks).

4th-7th December 2016
UKOUG Tech16 – UK Oracle User Group technical conference
This is “my conference” – the one I have been going to for 13 or 14 years, have presented at all but 1 or 2 of in that time and I now help organise. It is once more in Birmingham at the ICC and is being run alongside Apps16 and JDE16.
As I help organise the tech content (and this year I am the Tech 16 project lead) I have a lot to do before the event and duties when I am there, so I keep my presenting to a minimum. This year it is a single slot:
5th 09:00 The Heart of Oracle 12c -A review of How the Core RDBMS Works

Only now I am doing a roundtable too, about why developers suck and DBAs are arrogant:
… 18:45 DBA vs Developer Roundtable

15th-18th November
DOAG – German Oracle User Group 2016
I’m really happy to be going to DOAG for the first time. Since I decided to dedicate more time to overseas presenting I’ve felt I needed to be in the UK getting the UKOUG Tech conference ready at the time of year that DOAG occurs. But this year I decided to really try and make space for DOAG and I got papers accepted – online details here

11th-13th November

12th – Oslo, Bulk Data Processing methods with SQL and PL/SQL and
13th – Helsinki (I hope to get to see my friend Heil)

POUG -Polish Oracle User Group 1st international conference
This is the first international conference that the Polish Oracle User Group has organised and I’m very happy to be supporting it. It is organised in part by my friend Kamil, who owns the Polish “Ora600” company (nothing to do with me, lucky for them).
I’m doing two talks (that seem to be very popular with selection committees at present!):
7th 12:40 The Forgotten Performance Tuning Trick – Clustering Your Data
8th 12:40 Tips on Bulk Data Processing with SQL & PL/SQL

18th-22nd September 2016
Oracle Open World 2016
I think I have a slot in the popular lightening talks that the European user group does – 5 or 6 mins each until we run out time. The session is officially “EOUC Database ACES Share Their Favourite Database Things: Part I [UGF2630]” and “…part 2 [UGF2632]”. I will be on at the end if time allows, with an awesome talk on… something. But my main aim is to hit the slot time to the very second again…

19th-20th September 2016
OakTable World
This is held to the side of OOW16 (and yes, OOW16 know about it!). It is where the OakTable put on their own set of technical (and sometimes not-so-technical) talks as a nice balance to the official talks by Oracle. Expect less Cloud Froo-Froo and more real-world, technically deep stuff.
I offered to be the back-up presenter if someone had to drop out – and they have. So I’m going to talk about disasters.

1. coskan - November 7, 2009

“All my talks were rejected, but I’ll still be there ”

Just for curiosity what were they about ?

It would be nice to watch you presentations which I have never had chance to.

I will be there on Wednesday only because of recession 🙂 I hope I would catch you any of Tanel Poder sessions, I plan to attend all of them and as a last one I need to choose one of the last two between Wolfgang Breitling or Husnu Sensoys

2. Dird - May 29, 2015

http://oraclemidlands.com/archive?e=5 will bring up the #om5 event details. I need to add a “copy link” button.
Also, good to see you updated this page 🙂 it was on 2012 until a couple months ago?

mwidlake - May 29, 2015

Thanks Mike, I’ve updated the links. Yes, I failed to update this for a long time. I’m slowly refreshing bits of my online presence

Dird - May 29, 2015

Make sure you attend all the London events, it’s the only reason I know there’s been 4 so far 😛 They need a #loc5 / #cora5 tag to keep track
